Oh, I was confusing CCA with RELCACHE_FORCE_RELEASE, which does something
a bit different.  I wonder whether we should get rid of that symbol and
just drive the test in RelationClose off CLOBBER_CACHE_ALWAYS.
(Ditto for CATCACHE_FORCE_RELEASE.)  Or maybe make CLOBBER_CACHE_ALWAYS
#define the other two symbols.
